How many letters in the word 'DESTINATION' have as many letters between them and the start of the alphabet as they have between them and the end, when counted in the English alphabet?
The answer is none. The alphabet has 26 letters, so no letter has equal numbers of letters before and after it. The closest are M and N, which are unbalanced by one, and neither appears in DESTINATION.

Explanation
A letter has equal letters before and after it only at the middle position of the alphabet, and with 26 letters there is no single middle letter (M and N are the two central ones). For M, 12 precede it and 13 follow it, and for N, 13 precede it and 12 follow it. DESTINATION has no M or N and in any case no letter balances, so the count is none.
